Abstract:
A transition-metal-free electrochemical chalcogenative cyclization of 2-alkynyl aryl oxime with dichalcogenides has been established to assemble valuable 4-organochalcogen isoquinolines concisely. This protocol proceeds via constant electrolysis in a user-friendly undivided cell setup. It circumvents the necessity of transition metal catalysts, chemical oxidants, and harsh reaction conditions. The practical utilities of the current protocol were illustrated by excellent functional group tolerance, remarkable regio-selectivity, easy scalability, mild reaction conditions, and transformable 4-organochalcogen isoquinoline products.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of...
